#2 Predator-Prey?

[Anonymous]

Hi,
In all the ai and alife programs I know that have
predator prey relationships it is very hard to find a stable
relationship where extinction of one or the other doesn't
occur. Could you please give me some suggestions of
what parameters to use in aiplanet (an extremely good
program I would like to add) that will allow stability.
Thanks.
